Abstract

The invention discloses a whole vehicle energy distribution method, a system and an electric vehicle, comprising: setting energy use priority from high to low, sequentially including safety requirement, driving requirement and comfort requirement; Detecting an entire vehicle mode, wherein when the entire vehicle mode is a mileage mode, the required power for controlling the comfort requirement isless than a first preset value, wherein the entire vehicle mode comprises a mileage mode and a normal mode; obtaining The maximum discharge power of the power battery, and the allowable power of eachenergy use priority according to the maximum discharge power; Controlling the subsystem in the whole vehicle system to work according to the permissible power. Adding A mileage mode in the whole vehicle mode, According to the whole vehicle mode, the energy distribution scheme of the whole vehicle is made. In the low temperature limit environment, if the driver pursues the long mileage, the required power of the comfort demand is limited, which not only saves the electric energy of the power battery, but also can more flexibly carry out the energy distribution according to the driver's demand,and improve the driver's driving experience.
